You were hiding from the zombies in an abandoned hospital, all alone when all of a sudden a random guy burst into the room you were hiding. That random guy was your worst enemy.

He hit you several times and even shot you in the abdomen.

Leon Kennedy entered the same abandoned hospital after a few minutes and heard shouting and screaming. He knew that something was off and took his gun out looking through all the abandoned hospital's rooms while you shouted and cried in pain.
